News of the bold rescue garnered national attention for a brief time, but Swope's action did make a lasting impression on one primatologist who's spent her career working with chimpanzees.
Speaking to a crowd at the Woodrow Wilson International Center for Scholars in 2005, Jane Goodall referenced the incident and a conversation her institute's then-director had with Swope afterward:
"He called up Rick Swope and he said, 'That was a very brave thing you did. You must have known it was dangerous. Everyone was telling you. What made you do it?' And Rick said, 'Well, you see, I happened to look into his eyes, and it was like looking into the eyes of a man, and the message was, 'Won't anybody help me?'"
As Goodall notes in her full remarks, Jo-Jo's life was wrought with hardship, having been taken from the wild after his mother was killed by poachers - an all-too common story for countless chimps who long for people to see them as Swope had.
"If you see that look with your eyes, and you feel it in your heart, you have to jump in and try to help," she said.
